求翻译：随着光催化处理时间的增加，处理液DOM的保留时间延长，说明在光催化作用下DOM的高分子组分不断被破坏，小分子量组分持续增加。是什么意思？

With the increase in photocatalytic processing time, processing fluid retention time of the DOM extension, indicating the catalyst in the light of DOM polymer components continue to be destroyed, a small molecular weight components continued to increase.

With the increase in processing time light-catalyzed DOM dealing with fluid retention time extension of the optical catalyst DOM under the polymer Group continuously destroyed, small molecular weight Group continued to increase.

Along with the photochemical catalysis process time increase, the processing fluid DOM retention time lengthens, showed the DOM high polymer component is destroyed unceasingly under the photochemical catalysis function, the small molecular weight component increases continually.

As the photo-catalytic processing time increases, liquid retention time of the DOM extension, description of polymer components in photocatalysis DOM constantly destroyed, low molecular weight components continue to increase.

With the increase in photocatalytic processing time, processing fluid retention time of the DOM extension, indicating the catalyst in the light of DOM polymer components continue to be destroyed, a small molecular weight components continued to increase.
